The Porteur Rackbag in Blackout Patchwork is constructed from four hard-wearing, weatherproof materials — VX21 XPAC, X50 XPAC, 500D Cordura with 275 Dyneema Ripstop, and 1050D Ballistic Nylon — arranged in a gradient from heaviest at the base to lightest at the top to optimize durability where it matters most. The tonal blackout aesthetic brings together panels of varying textures and finishes for a visually cohesive, technical look. Designed for compatibility with most standard porteur racks including Pass & Stow, Velo Orange, Soma, and Surly.
